2 Claims.

This invention relates to improvements in the construction of heat insulating walls for buildings of the type embodying a packing ofrock wool or equivalent fibrous heat insulating material. The primary object of the present invention is to provide a heat insulating wall of the above kind wherein simple and eiilcient provision is made to prevent sweating and moisture getting into the fibrous heat insulating material. y

Another important object of the present invention is to provide a heat insulating wall of the above kind with a most simple and efficient means for sustaining the fibro-us insulating material so that it will not unduly settle and pack down so as to leave objectionable open spaces 'and cause other objectionable results.

With the above general objects in view, the present invention consists in the novel form, combination and arrangement of parts hereinafter g.) more fully described, shown in the accompanying drawings, and claimed.

In the drawings:

Figure 1 is a fragmentary vertical sectional view through a heat insulating wall embodying gg the present invention, the wall being partly broken away.

Figure-2 is a fragmentary horizontal section taken on the plane oi line 2--2 of Figure 1.

Figure 3 is an inside fragmentary elevational so view of the wall shown in Figure 1, with the inner wall member and fibrous packing omitted.

Figure 4 is a'perspective view of one of the devices for sustaining the fibrous insulating material, shown in Figures 1, 2 and 3.

$5 Figure 5 is a 'i-ew somewhat similar to Figure 1 of a modified form of wall construction embodying the present invention.

Figure 6 is a fragmentary horizontal section taken on the plane of line 6-6 of Figure 5.

Figure 'I -is a view similar to Figure 3 of the wall shown in Figure 5.

Figure 8 is a perspective view of one of the devices for sustaining the fibrous insulating material, as shown in Figures 5 to 7 inclusive; and

through the corrugated cardboard used in Figures 1 and 5 as a backing for the fibrous insulating material to prevent sweating and moisture getting into said fibrous insulating material.

Referring to Figures 1 to 4 inclusive, the wall, except at pointsbetween adjacent stories, inciudes spaced inner and outer wall members 5 and B, and has an outer brick facing l suitably tied to the wall proper as well as spaced from the outer wall member 8 to leave an air space s Figure 9 is a fragmentary longitudinal section between said outer`wall member 5 and said facing l. The wall proper includes the usual frame composed of horizontal joists 9 and vertical studs I0, the inner wall member 5 consisting of lathing and plaster as usual anchored to the studs I0, and the outer wall member 6 consisting of the usual wood siding. l

In accordance with the present invention, I provide in the space between each pair of adjacent studs I0 and between the inner and outer wall members 5 and 6 an intermediate lining or backing II of relatively stiff corrugated cardboard or equivalent insulating sheet material. Except at the point between adjacent stories, the packing of rock wool or equivalent brous insulating material is placed as indicated at I2 between the inner wall member 5 and the intermediate lining or backing II. Anair space I3 is thus left between the intermediate lining or backing II and the outer wall memberi, and the outer surface of the packing I2 is thus lbacked by the lining or backing II `so as to prevent sweating and moisture getting into the fibrous packing material I2.

The backing or lining II may consist of superposed hanged sections nailed through their edge flanges to the adjacent joists 9 and studs I Il.

In order to prevent the fibrous insulating material I 2 from unduly settling and packing down, I provide at suitable elevated points between each pair of adjacent studs III andbetween the inner and outer wall members 5 and 6, horizontal partitions I4 formed of strips of corrugated cardboard. 'I'hese partitions I4 are required to be somewhat stiffer and stronger than the lining or backing I2, and for this reason the lining or backing I2 may be formed of corrugated cardboard made up of a single layer of fiat paper and a layer of corrugated paper as shown in Figure 9, while the packing supports or partitions I4 are preferably formed of corrugated cardboard made of two layers of fiat paper separated by corrugated paper. As shown in Figure 1, the supports or partitions I 4 may bearranged between superposed sections of the lining or backing II and extended outwardly of the latter to divide the air space I 3 and prevent convectional air currents in the latter. Also, the partitions or supports Il are at least provided with end flanges l5 to facilitate nailing thereof to the inner side of the outer wall member I. In that case, the backing lla is provided inwardly of and in spaced relation to the floor joist I8 so as to provide the spacein which the packing Ila is placed.

Referring in detail to Figures 5 to 8 inclusive, the inner wall member 5a is composed of laths and plaster as usual and attached to the vertical studs "la, the outer wall member Sa being in the form of masonry and spaced from the intermediate lining or backing ila to provide an air space I3a between said lining or backing ila and said outer wall member 8a. In this case, the fibrous insulating material or packing I2' is placed between the intermediate lining or backing lla and the inner wall member 5a. Also, the horizontal packing supports or partitions Ila are providedbetween each pair of adjacent studs Illa, but only extend outwardly to the intermediate lining or packing Ila so as to merely divide the space between said lining or backing lia and the inner wall member 5a. In this embodiment, the partitions or packing supports Ila are not only shown as provided with end ilanges lia for attachment to the adjacent studs Ilia, but also have a further ilange I 9 along one longitudinal edge for attachment and reinforcing purposes, the ends of the ilange I9 having extensions 2l lapped upon and secured to the end ilanges lia. The longitudinal flange i8 of each packing support or partition I la may be attached to the intermediate lining or backing Ila, or if this form of partition or packing support is used in a wall oi' the type shown in Figure 1, such flange il may be nailed to the outer wall member 6. Obviously, the packing supports or partitions I l or ila may be disposed either with their flanges projecting upwardly or with said anges projecting downwardly.

In constructing a wall in accordance with the present invention, the brous insulating material is of course placed between the inner wall member and the intermediate lining or backing untilit reaches a predetermined height, whereupon a pachngsupport or partition is installed. The placing of the fibrous insulating material between the inner wall member and the intermediate lining or backing is then continued above this support or partition. Obviously, the number of packing supports or partitions and their distance oi spacing apart vertically may be varied to suit' requirements such as variations in the width of the space between the inner wall member and the intermediate lining or backing, etc.

In view of the foregoing, it will be seen that I have provided a most simple, inexpensive, and l eective means for backing the fibrous insulating ber, an intermediate backing of corrugated cardboard extending between each pair of adjacent studs and spaced from the inner and outer wall members, a packing of ilbrous insulating material illling the space between said intermediate backing and said inner wall member, and horizontal partitions oi corrugated cardboard between the inner and outer wall members to prevent settling of said fibrous insulating material and to prevent convectional air currents in the space between said backing and the outer wall member, said partitions having end flanges nailed to said studs.

A heat insulating wall including a frame composed of horizontal joists and vertical studs. an outer wall member at the outer side of said frame, an inner wall member at the inner side of said frame and spaced from said outer wall member, an intermediate backing of corrugated cardboard extending between each pair of adjacent studs and spaced from the inner and outer wall members, a packing of fibrous insulating material nlling the space between said intermediate backing.

H`and said inner wall member, .and horizontal par- FLOYD CHARLES Ranma.
